feat: include information about text range changes in onChange

[hannojg]

Summary:

This Pr provides a solution to:

• TextInput desynchronizes with its native counterpart #37722

By providing further information about the range in which a text has been changed in the onChange event users are able to implement <TextInputs /> that only apply partial text updates, thus avoiding race condition issues between the main/UI and JS thread.

Changelog:

[ANDROID] [ADDED] - Add start, before, count info to the Textinput's onChange event
[IOS] [ADDED] - Add start, before, count info to the Textinput's onChange event

Test Plan:

I added an example to the rn-tester app.
